SPECIFICATION forming part of Letters Patent No. 314:,782, dated March. 31, 1885.

Application filed December 19, 1884. (No model.)

.To @ZZ whom, t may concern:

Beitknown that I, DAVID EJBEDELL, a citizen ofthe United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichr it appertains to make and use the same, referand to letters of reference marked thereon,

which form a part of this specification.

The object of my invention is to provide an automatically-acting catch or holding device for windows, also adaptedto act as a fastening or locking device for the same; and it consists of a rotating plate arranged in a frame or casing secured in or upon the window-- casing, or in or upon the sash-frame, adapted to engage with teeth or stops upon either the sash or casing, as described hereinafter, and a spring or equivalent mechanism operyating to cause the said rotating plate to engage with the teeth or stops.

In theaccompanying drawings, in which my invention is illustrated, Figure l is an elevation of a portion of the window-casing and the lower sash, partly in section, showing an arrangement of my catch, &c. Fig. 2 is a View similar to Fig. l, but with half of the mortisecasing removed, said figure showing the operation of the ringer-piece and bolt upon the angular plate. Fig. 3 is an elevation of a portion of a car-window and window-casing having my catching mechanism thereon. Fig. 4 is an enlarged view of the fastening shown in Fig. 3, with the top or`face of the casing broken away, showing the operation of the angular plate under certain conditions, described hereinafter. Fig. 5 is asectional view showing one form of construction of a carwindow fastening with the recess in the under plate for the finger mechanism. Fig. Gis a view of back or under side of the casing, tc., shown in Fig. 5. Fig. 7 lis a side elevation of a skeleton frame, Src.; and Fig. 8 is a back View of Fig. 7.

The catching or holding plate A, as indicated in the drawings7 is provided with journals a, and arrangedin a slotted casing or frame, B,the journals moving inthe slots in said casing or frame.` The preferredoform of the plate A is square; but it may be circular, with catching-points upon its sides or periphery, or polygonal, or any desired form, the intention being to provide a plate or catch adapted to rotate, having projections or corners to engage with and catch upon teeth or stops suitablyplaced so as to hold the window or sash in any desired position. The

form which gives the best results, both in re-` which varies with the weight of the window.

In Fig. l is shown an arrangement and construction adapted for ordinary house-window sashes. In this instance the rotating piece or plate A is arranged in a slotted casing mortised in the side frame of the windows, the spring being arranged between the said plate A and the back of the casing B, as indicated in Fig. 2. Fig. 8 shows the device as arranged upon the window orsash, as ina carwindow, the form and arrangement of the1 casing being changed to meet the different conditions which will be described below, the arrangement of the spring, as indicated in Fig. 4,' being similar to that in the mortised casing. y

Illustrated in Fig. 7 is a skeleton casing or frame, which may be mortised in the usual manner, consisting of the face-plate E, provided With an aperture through which the rotating plate mcves, and having slotted plates d, within which the journals of the rotating plate work, and a spring, d', engaging with the rotating plate, said spring being secured to the face-plate by riveting, or perforated to receive the lug d, and held in place by a pin, d3, or in any suitable manner. This last formviz., the skeleton frame, tc-is of the most simple construction and very cheaply made, and hence is adapted for general use.

As a simple catch,the device operates-in the following manner: Upon a ear-window the ser- ICO rated piece O is preferably placed, as in Fig. 3, l

pressure of the spring causes it to spring auv tomatically into the notch below. To lower the sash entirely causes a succession of revolutions in theplate, depending upon the number of teeth in the plate C. The strength of the spring in relation to the window is alittle in excess of that required to hold the plate .within the notches to prevent the sash falling. This surplus force is overcome by the p erson in lowering the window. When the serrated plate is secured to the sash and the rotating plate to the window-frame, the position of the teeth is reversed. as indicated in Fig. 1, so that plate A will catch thereupon, the action of the same being like that described above. l

As thus constructed and operating, it will be seen that as a simple catch the device is perfectly automatic. needing no manipulation to operate it aside from the ordinary raising and lowering of the sash.

.To employ the plate A as a fastening device. in addition to its action as a simple catch, I

provide a stop 0r mortise, m, in the lower part the rotating plate is projected by the spring andfnormally locks the window, as indicated in Figs. l and 3.

To .disengage the plate A from the stop ormortise necessitates the employment of mechanism adapted for the purpose. The preferred method of constructing the said unlocking mechanism is so that it alsol acts as a. lifting-piece in raising the sash. In Fig. 1 is shown one construction adapted for ahouse-- window,consist.ing ol' a lever, g, pivoted to an escutcheon g. On the inside of the sash, a bolt, g2, is pivoted to one end of the lever and passes through the plate G into the lower part of the mortise m, where it engages the lower part of the plate A, as indicated in Fig. l. The rotating plate is disengaged from lthe mortise by lifting the lever,wh1ch presses the bolt against the lower part of the plate A until said plate clears the lower corner ofthe mortise, as indicated in Fig. 2, when the sash can be raised.

Tolapply the unlocking mechanism upon the n ppcr sash necessitates a reversal of the finger-lever, as in that case the sash descends.

Upon ca1 'windo\vs the unlocking mechanism is preferably. arranged on the casing of the rotating plate, and so constructed that the act of lifting the sash by the nger-lever and the ordinary xed lifting-handle withdraws the rotating plate from the mortise.

In the form shown in Fig. 5 the casing consists of two plates,h h', the under one of which, hfis so formed as to provide a recess within which the inger'piece, Svc., is arranged, the unlocking mechanism consisting of said finger-piece t', pivoted to the under plate, h', and a slotted piece, il', which engages with one of thejournals ofthe rotating plate.

I do notwish to be understood as limiting myself to either of the'devices for operating the catch or rotating plate, ,as equivalent means acting by gravity, Snc., may be used therefor. plate upon the spring eauses it to becomel worn at the central portion thereof, and conse,- quently weakened. To prevent this I lnay use a supplemental plate, p, interposed between the rotating plate and spring, as illustratedY in Fig. 2, attached to a post, or otherwise secured.

Arranged and constructed as above described, the plate can automatically adjust The constant action ofthe rotating itself to the notches and mortise in the serf f the mortise when the sash reaches its closed.

position.

Having thus described my invention, what ,u

I claim as new is-fp 1 A sash holding or fastening device provided with a rotating plat'evarranged within a slotted frame or casing, and adapted to engage with stops suitably placed to lock or hold the sash, saidrplate having `journals moving in the slots in said frame or casing, and a spring ar. anged and operating to cause said rotating plate to engage with said stops, substantially as and for the purpose set forth.

2. The combination, in a sash holding or fastening device, with a rotating plate arrangedwithin a suitable casing, a spring, land stopsu in, a spring arranged in connectionwith the A casing to .cause thesquare rotating plate to engage with the stop-plate, and mechanism, substantially as specified, whereby the said rotating plate is disengaged from locking-en- Y gagement with the stop-plate,`ior the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 29th day of November, 18844.
